먼저, 일반적인 의안의 제조방법은 다음과 같다.First, a general method of manufacturing a bill is as follows.
의안 본뜨기용 기구를 이용하여 의안이 삽입될 안와의 결막낭 부분에 몰딩재를 주입하여 의안본을 조성하는 데, 상기 몰딩재는 주로 치과에서 치형본을 뜨는데 사용하는 알지네트(ALGINATE)를 사용한다.The molding material is injected into the conjunctival sac portion of the orbit to be inserted into the eyebrow using the eyebrow tool, and the molding material uses ALGINATE which is used mainly for dental bone formation in the dentist.
이렇게 조성된 의안본을 상하형 플라스크에 넣고 매몰하여 의안의 음형을 조성하고, 이 음형에 불투명 수지재로서 고순도 아크릴 수지(PMMA: Poly Methylmethacrylate)를 주입 경화시켜 비로소 안와에 삽입될 의안체를 만들어내게 된다.The eyebone pattern thus formed was buried in a vertical type flask to form a sound pattern of the eyebone, and a high purity acrylic resin (PMMA: Poly Methylmethacrylate) was injected and cured as an opaque resin material to form the eyebone to be inserted into the orbit do.
그리고 이 의안체에 연마과정과 광택처리과정을 거친 후 표면에 실제 눈의 모양 및 색채와 같도록 눈동자와 흰자위의 핏줄 등을 수작업으로 그려 넣어 완성하게 된다.Then, the eyebrows are polished and polished, and then the eyeballs and the white blood vessels are manually drawn on the surface so as to match the shapes and colors of the actual eyes.
상기 눈동자(홍채)는 의안에서 가장 핵심적인 부분으로서, 각 개인마다 독특한 특징이 있으며, 매우 정교한 형상과 색채를 지니고 있고 사람의 인상을 결정하는 주요한 부분이다.The pupil (iris) is the most important part of the body, and each person has a unique characteristic, has a very sophisticated shape and color, and is a major part of determining the impression of a person.
상기와 같이, 수작업으로 인공의안을 제작하는 것은, 제작에 대한 소요시간이 길고, 환자의 눈에 적합하도록 제작하는 것이 어렵고, 비용면에서 경제적이지 못하다.As described above, it is difficult to manufacture the artificial eye by hand, because it takes a long time to manufacture it, and it is difficult to manufacture the eye artificial eye to fit the eye of the patient, and it is not economical in cost.
따라서, 수작업이 아닌, 3차원 프린팅을 통한 인공의안 제작 시, 제작 소요시간이 짧고, 환자의 눈에 적합하도록 제작되며, 비용면에서 경제적이다.Therefore, when making an artificial eye through 3D printing rather than manual, it takes a short time to manufacture, is manufactured to fit the eyes of the patient, and is economical in cost.
